solor panelling? Answered

How do you store the energy you get from solar panels. Tell me what device or part i need to connect to the solar panels to store the energy to use it later on in the day aftter the sun is out?

You store the energy in a battery. The best type to use are sealed lead-acid "Deep Cycle" marine batteries. You can drain them down lower than standard batteries.

Decide how many you will need to power whatever your project is and connect them together.

For a smaller solar power station, you can use the sealed lead-acid deep cycles or GEL batteries, but you will need a special charge controller. GEL batteries are commonly found in mobility stores as wheelchair or scooter batteries.

No matter what battery you use, you will need a charge controller of some sort to feed the batteries energy that they can handle from the solar panel. And, if you require AC power (like in a house) you will need an inverter to change the DC power from the battery to AC power.

Yup, that's pretty much it. The only thing I can add is that the charge controller and inverter must be large enough to handle the maximum load you're expecting them to see. In the case of the charge controller, it must be able to handle the peak power produced by the solar cells, plus a bit of margin. The inverter must be able to handle the current draw of all the devices connected to it (or it will likely shut itself off, or go into current-limit mode).

Commercial Solar Panels are Expensive!
Fact: It will take you more than 10 years to pay back
Solution: Using Surplus Solar Cells You can get pay back in 1-2 years

A battery, usually Lead-acid, like a car battery.
